Peter Maydell 9793212bb0 hw/irq: Add qemu_irq_split() so one GPIO output can feed two inputs ...

Add a qemu_irq_split() function which allows a board to wire a single
GPIO output up to two GPIO inputs. This is needed for realview boards,
where the MMC card status is visible both in a system register and
via a PL061 GPIO module.
